Superior Cerebellar Peduncle (Anterior; Left)

Quick Facts

The superior cerebellar peduncle (aka rostral cerebellar peduncle, or brachium conjunctivum) consists of a large bundle of nerve fibers emerges from the cerebellum along the lateral wall of the fourth ventricle into the tegmentum where most of its fibers decussate.

The fibers originate from the dentate and interpositus nuclei. They terminate in the contralateral red nucleus and parts of the ventrolateral, ventral intermediate and central lateral nuclei of the thalamus.
